BRAKE DEVICE WITH ELECTROMECHANICAL ACTUATION

摘要

The invention relates to an elevator system having an elevator car (2) displaceably disposed along at least two guide rails (6), and the elevator car (2) has a brake system having preferably two elevator brakes (20). The elevator brake device (20) includes a brake housing (21) and an energy accumulator (24). The brake housing (21) is mounted in a vertically displaceable manner, or such that it can be displaced in a longitudinal direction and in parallel relative to a brake direction between a first position (B1) and a second position (B2). The energy accumulator (24) acts upon the brake housing (21) and displaces the brake housing in the direction of a second position (B2). The elevator brake device (20) further comprises an actuator (32) that can act upon the brake housing (21) and is designed to retain the brake housing in a first position (B1). In its first position (P1), the actuator can retain the brake housing (21) in the first position (B1) against the force (F24) of the energy accumulator (24). In its second position (P2), the actuator allows displacing the brake housing (21) into the second position (B2). In this way, a brake element (25) is brought into contact with the brake rail (7).
